Method for retransmitting satellite data transmission data

The invention provides a satellite data transmission data retransmission method, and relates to the technical field of satellite data transmission, and the method comprises the steps: S1, a ground station sends a data retransmission request to a satellite; s2, the spaceborne software receives the injection number and judges the legality of the injection number, if the injection number is legal, the step S3 is executed, otherwise, the injection number is discarded, and no processing is performed; s3, enabling the satellite-borne software to enter a retransmission mode, and controlling the data transmission single machine to complete data retransmission in a specified range; and S4, the satellite-borne software recovers to a normal data playback mode after completing data retransmission. According to the method, the availability of satellite data can be improved, and the method plays a positive role in improving the service capability of satellites. 本发明提供了一种卫星数传数据的重传方法，涉及卫星数传技术领域，该方法包括：步骤S1：由地面站向卫星发送请求数据重传的注数；步
